Be a known that 1, JAMES wnwsi a citizen of the LUnited States, residing at" Hammond, in the county of Lake and State of Indiana, have invented certain new and useful Improvements-in, Two-Part Reversible Brake-Beam Fulcrums, of which the follow ing is a specification.

My invention relates to brake-beam fulcrums," especially-tothose of the reversible I type, and itsobject is the'production of a .two-pieceiulcrum which shall be extremely e in construction, and of whichthe osci' latory; bar-rel to -which the "operat ng si n lever is: pivoted is held in-placeland main engaging portion of the fulcrumzisremoved or unclamp'ed from the beam. This barrel is inserted in the companionpa rtof the de-. )7106 through a comparatively large a erture in that part of the fnl'crum'adapter to lie against the flanges of the brake beam, whereby when the device is fastened to. the

merit-of my invention, and, in the various views, like reference characters refer-to the same parts throughout.

and Fig. 4 is a top 'pla'n'viewfof the device, The fulcrurn includes rtwo parts, one of whichis fastened to the brake bealn, while the other part is ,revoluble in the first'part v -apart sufiiciently to receive the-brake ,ean'r and is adapted to have the- -operating lever ;j pivoted thereto; Thepart intended tolb'esecuredjto the beani has abase'510, projecting from which is a pair of oppositely-dis posed flange-engaging hooks. 11 and 12 these hooks or gripping lugsbeing siaced between them. After the beam-has once been inserted between them, by turning the member, the gripping lugs may be brought into 006 erative relation with the flanges of the I rake beam 13. At its outer end,

each of these hooks or gripping lugs has a flat terminal portion'14, the two parts being adapted to lie against thefweb of beam 13 and, onopposite. sides thereof. -These ears 14 are' ape'rtured as illustrated,"and -are 'ada ted to be-fastened to the web of the bra re'beam'by means of rivets,-as is obvious.

In order to strengthen these flange-engaging lugs, each is provided with integral marginal ribsor beads 15, clearly shown on:

Figs. '1, 3 and 4 Projecting in the opposite directionfrom the base 1 0 isja yoke or stirrup 16 held in place by a air of integral brackets '17. At its outer en'c -this yoke is enlarged at 18, and is oentrally andccircularly apertured at 19to form a bearing. The base 10 of this member, which in normal {positionlies a ainstthe oppositely-extended flanges "13 o the brake beam, has a' comparatively large round aperture-20,- the diameter of whichis at least equal to the greatest -'crosssectional dimension of the barrel described below. v

' ;The barrel or reversible part of the'fuljcrum-has atone end a round ournal-or plate 210i substantially thesame diame'ter as the a erture. 20-, and adapted to'fit and turn erein. At its '0 posite end, this barrel has a similar round p ate 22, from the outer facev ofwhic'h rojects-a smaller integral journal or stub s aft-23 vintended to fit and rotateg'ral therewith, is a pair of fiat-plate members "2 4' 24--adapted to receivebetween theinthe brake-operatingFlever 25, a portion of which is indicated. in ig. ,3. Round holes '26 are in the hole-1 9 of'the yoke or stirrup loi Co'nnecting the two plates 21 and'22, and inteprovided the -Iner nbers;24,;and in alinement, through which maybe passed the hinge fbolt orrivet '27- which' fastens the lever '25 in the fulcrum. -In order to apply thisreversible fulcrum to the brake beam, the. barrel is'inserted within its companion supportin member through the'aperture' 20, and w on fully inserted the journals 21 and '23 neatly'fit, within their bearings 20 and 19, so thatthe barrel maybeoscillated or turned to accommodate operating levers dis osed at various angles. After the barrel asbeen' introduced into the main member of the fulcrum, the latter is ap lied to the brake beam in such a mann'er t at the brake beam passes between the flange-enaging lugs or hooks 11 and 12, and then,- I y turnin the fulcrum, the lugs Hand 12 are broug t into flange-gripping position,

and the ears )14 die fiat against opposite-sides of the beam web, to Whichthey maybe riv-' Vet ed. The fulcrum is now in position for operation, and as soon'a's the'lever'25 has been bolted or riveted between the pair of vents its accidental displacement or removal" from its supporting yoke or stirrup. As soon, however, as the mam body of t 1e fulcrum has. been detached from the brake parts of the fulcrum 'Without departing from i beam, thebarrel can be readily removed by passin it through the aperture-20. i

To t oseskilled in the art it will- .be apparhthe spiritof my invention.

, As illustrated, my improved device consists only of two members, but it'will be a arentthat. these two members may e built up or constructed of a number of parts fastened together, if desired.

-I claim:- v
